Researchers Find How Tiny Plastics Slip Through The Environment
Washington State University researchers have shown the fundamental mechanisms that allow tiny pieces of plastic bags and foam packaging at the nanoscale to move through the environment.
The researchers found that a silica surface such as sand has little effect on slowing down the movement of the plastics, but that natural organic matter resulting from decomposition of plant and animal remains can either temporarily or permanently trap the nanoscale plastic particles, depending on the type of plastics.
The work, published in the journal Water Research, could help researchers develop better ways to filter out and clean up pervasive plastics from the environment. The researchers include Indranil Chowdhury, assistant professor in WSU’s Department of Civil and Environmental Engineering, along with Mehnaz Shams and Iftaykhairul Alam, recent graduates of the civil engineering program.
